Home-Based Training With Feedback to Improve Outcomes in Adolescents and Young Adults With Cerebral Palsy..

Condition(s) studied

Investigational drug(s) / intervention(s)

Music Motion Group: Participants will engage in personalized, home-based motor training programs tailored to their individual goals. Each will wear a wireless Inertial Measurement Unit (IMU) on the targeted body part, which transmits movement data via Bluetooth to a tablet app. The training emphasizes task specificity and intensity, with five virtual check-ins to review progress and adjust training parameters. The intervention studied is extrinsic feedback; the app analyzes movement data and provides feedback through music. Before each training session, the app guides participants to set personalized intensity thresholds based on current capacity. When participants meet the intensity threshold, musical elements (e.g., drumbeats, vocals) play. If they fall short, elements drop out, providing knowledge of erroneous performance.

Control: Participants will follow personalized, home-based motor training programs designed like the Music motion group. They will wear a wireless Inertial Measurement Unit (IMU) on the targeted body part, transmitting movement data via Bluetooth to a tablet app. However, unlike the Music Motion Feedback group, participants in the Control group will not receive any extrinsic feedback during their training.

Study summary

This clinical trial aims to determine whether extrinsic feedback through music enhances the effects of home-based motor training for adolescents and young adults with cerebral palsy (CP) and whether feedback improves adherence to the training program.

The main questions it aims to answer are:

* Does extrinsic feedback improve real-world movement more than home training alone?
* Do participants receiving extrinsic feedback adhere more closely to their training program?

To determine its effectiveness, the investigators will compare home-based training with and without real-time music feedback.

Participants will:

* Engage in a home-based motor training program for 12 weeks, tailored to their individual needs and goals.
* Receive real-time music feedback during training or no feedback (control group).
* Attend weekly virtual coaching sessions to discuss short-term goals and training progress.
* Undergo movement assessments before training, at 12 weeks (T2) and 24 weeks (T3).
* Wear movement sensors for 72 hours at T2 and T3 to track real-world movement behavior.

Eligibility

Primary outcome measure(s)

• Percentage change in daytime movement of the trained extremity (right or left arm or leg) as measured by 3-axis accelerometer and gyroscope data analyzed via deep-learning neural network — Baseline, at 12 weeks (end of intervention period), and at 24 weeks (long term follow up)
  Movement data will be collected using seven Inertial Measurement Units (IMUs) worn continuously for 72 hours at three time points: baseline, 12 weeks (end of intervention), and 24 weeks (follow-up). IMUs will be attached to the sternum, wrists, thighs, and lower legs using adhesive patches and will capture 3-axis accelerometer and gyroscope data. A validated custom neural network (Novosel et al. 2023) will convert signals into images and analyze them using convolutional layers to extract features related to movement behaviors. The primary metric will be the percentage change (minutes a day) in real-world daytime movement of the trained limb, computed relative to baseline. This outcome reflects changes in functional mobility resulting from the motor training intervention.
